Elements are slideshow & three short legs below it, no scrolling at 1024 x 786, and X most recent blog posts. If we use Oxygen theme, slideshow images are sticky posts. Other themes that support home page slider probably work similarly.
Three short legs each contain thumbnail image & text blub: (1) Adoptable Pets, blurb links to framed Petfinder page (2) Our Method, blurb links to Our Method & Success Stories (3) Our Success Depends on YOU ñ 501c3, no gov/HSUS or HSOCO support; links to Membership and Contributions pages. Slideshow can link to pages; need to be able to rotate/alter slideshow easily. Maybe add widget for calendar of events if you have a lot of events.
